vMy inventionrelates to improvements in coal mine car cagers, and has for its object to' provide simple-and comparatively inex- "pensiveinechanism for automatically cagingfniine cars and stopping and holding approaching'c'ars so thatthey may be c'aused to advance at intervals 'over' a gravity track approaching to the "mine vcages. A A'furtherobject "of theinvention is the provision of a mine car-eager th'atwill be automatic 3 in its operations with the as- I cending'movement'of'mine cages and thereby prove highly v tended. v I v 7 With the above and other objects in view, the "invention consists in'the novel -features eff cient for the purpose inofconstruction, arrangementand comb-inationof parts hereinafter more ,fully described and finally pointed out in the claims hereto appended; v I Referring to theaccompanying drawings f forming a'part'of this specification wherein like characters of reference denote similar "parts throughoutthe" several viewsz' v Fig.1',' is aa'planview 'of my automatic 5 coal mine car ca'ging device" shown as a twin approach equipment to the mine cages within'the sump. i Fig. 2; is ayvie'wtaken on line 22 of Fig 1 in direction of the arrow.

- The two roclcpshafts l 6"are connected v means of a suitable connecting rod-r10 7 through the -'medium of the arms 11, oneof which a descends from i the "forward: end "of each rock shaft 6. The'connecting rodall) is pivotally connected'at each end', as"at12 to the descending' arms 11'ofItherock shafts 6,*as clearly shown, in Fig. 4,

The forward end of each rockshaft provided'--with' a short. shaft '13 =joi1rna1ed inthe bearing lk'and hin edly' -connected to the shafts 6, as at 15. he short shafts Interposed between each -'nut 16- andiithe bearing {lends-a coiled spring 16 which en circles each stub shaft 13 and acts as ra shock i'absorber to reduce the shock-when. the ears obviate the necessity ofperfectfalignment 13, are each screw'threaded, attheiouter end ing'position and move the car stops out of car holding position into car-holding position. 1

3. In a mine car eager, a pair of rocker shafts mounted'between the rails of two inclined tracks, a pair of car stops fixed to each rocker shaft, said stops being so arranged so that one stop will be out of car holding position When the other stop of said rocker shaft is in car holding position, meansfor connecting the two rocker shafts so they will move in unison, movable car actuated means operating When moved by a descending mine cage to place the car stops ing position into car holding position,jand .means connected to one end of each rocker shaft to act as ashock absorber to reduce the shock imparted tothe rocker shaft when a mine car strikes the car holding stops in theirapproach to the mine'cages and to obviate the necessity of perfect alignment of the rocker shafts.

In testimony whereof, I have hereunto signed my name to the specification FERDINAND F. BRASCHE.
